Mozilla has released Firefox 7. Unlike releases of Firefox 5 and Firefox 6 which were relatively minor upgrades to the browser, Firefox 7 includes a number of significant improvements, most important of which is probably the drastically reduced memory usage.

I'm getting 15% less memory at launch, and 30% less after some time goes by.

More importantly, it stays much more responsive over time. It's still not quite at Chrome-like levels of responsiveness, but it's getting much closer.

Oh, and to all the people complaining about version numbers: just go away and use another browser if you hate it so much. The whole point Mozilla is making is that you shouldn't care what the version is, just like with Chrome. They are working on making it silently update, that just hasn't come out yet.

I, for one, am very, very happy that these improvements that have come out over the last few months are available. Otherwise, we would all still be stuck on Firefox 4 for the next 12 months, and in comparison with the current version that would SUCK.
